What is error code 272 in Roblox?
Error code 272 in Roblox is a disconnection issue that prevents you from joining an experience.
It typically happens because you have a Chrome extension preventing the experience from launching.
The error code can also be caused if you are running an exploit, mod, or Roblox in 32-bit.
